CAE-based fatigue analysis

nCode DesignLife is an up-front design tool that identifies critical locations and calculates realistic fatigue lives from leading finite element (FE) results for both metals and composites. Design engineers can go beyond performing simplified stress analysis and avoid under- or over-designing products by simulating actual loading conditions to avoid costly design changes.

Product options containing functions for virtual shaker testing, fatigue of welds, vibration fatigue, crack growth detection, fatigue of composites, thermo-mechanical fatigue analysis and more are described below. 

  • Advanced technology for multiaxial, welds, short-fibre composite, vibration, crack growth, thermo-mechanical fatigue...
  • Intuitive, graphical interface for performing fatigue analysis from leading FEA results data, including ANSYS, Nastran, Abaqus, Altair OptiStruct, LS-Dyna and others
  • Multi-threaded and distributed processing capabilities for processing large finite element models and complete usage schedules
  • Single environment for correlating CAE directly with physical test data
  • Reduce reliance on physical test and avoid costly design and tooling changes
  • Perform smarter and quicker physical tests by simulating first
  • Decrease warranty claims by reducing failures
  • Reduce cost and weight by assessing more design options
  • Improve consistency and quality with standardized analysis processes
  • Highly configureable for the expert user
The following courses feature hands-on examples with DesignLife:

Attendees looking to learn more about the background of fatigue theory are encouraged to attend our 2-day course called Practical Fatigue Theory.

DesignLife Base

Virtual Strain Gauge and Virtual Sensor 
Enables correlation between test and finite element results. Gauges (single or rosette) or displacement sensors may be graphically positioned and oriented on finite models as a post-processing step. Time histories due to applied loads can be extracted for direct correlation with your measured strain or displacement data.

Crack Growth
Provides a complete fracture mechanics capability using industry standard methodologies for specified locations on an FE model. Built-in growth laws include NASGRO, Forman, Paris, Walker and more. Select from a pre-populated library of geometries or supply custom stress intensity factors.

Signal Processing 
nCode Fundamentals is included for basic data manipulation, analysis and visualization. Duty cycles can be defined by selecting from and building multiple cases. This feature makes it easy to create a composite duty cycle with repeats.

Materials Manager 
Enables materials data to be added, edited and plotted. A standard database with fatigue properties for many commonly used materials is included.

Custom Analysis
Enables Python or MATLAB scripts to be used to extend existing analysis capabilities - perfect for proprietary methods or research projects.

FE-Display 
Enables the graphical display of FE models with contours of stress results. Animating displacements from FE results or animation files display structural deformation under load.

Vibration Manager
Enables vibration specification data to be entered, edited, and viewed. A standard database containing over 100 vibration entries is included.
